Shop by Bike, funded by a mini-grant from the CarSmart Communities program of the Seattle's Strategic Planning Office (since re-org'd), was a project focusing on bike parking at Seattle's supermarkets. Volunteers in various neighborhoods biked to nearby Seattle supermarkets, armed with a checklist and a camera, and evaluated bike access and bike parking there. That was in 2001. Various bike-parking bloopers were observed. A letter was then sent to each of the 72 supermarkets, with store-specific suggestions for improving bike parking, where needed. In 2002, the stores were reevaluted. Some actually followed our handy advice -- nice. I'll post a photo album including some "before" and "after" pictures.
As an added thing, with the idea of encouraging bicycling for errand trips such as grocery shopping, people attending Bike to Work Day booths or Bike Expo in 2002 got handy shopping list pads and/or hip, safety-enhancing in-spoke reflectors with the cool Shop by Bike logo (a Chicago/Chicagoland Bike Fed creation).
